Specification of Letters Patent.

Patented July s, 191e.

Application led August 3, 1917. Serial No. 184,341.

clare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The invention relates to a knitted fabric and the method of knitting the same.

The object of the invention is to provide a novel and improved anti-run-back course in the body of a plain knitted fabric, as, for instance, in the leg of a stocking, which will effectively prevent a line of stitches from raveling or running beyond this course in y away of stitches in the fabric, and which will not materially affect the appearance of the fabric.

To this end the invention comprises the knitted fabric and the method of knitting the same hereinafter described and set forth in the-claims, the advantages of which will be apparent to those skilled in the art from an inspection of the accompanying drawing and the following detailed description of the fabric and method illustrated therein.

In the drawings, Figure 1 is a diagrammatic view showing a fragment of a knitted web which illustrates one form of the invention, and Fig. 2 is a similar view of a modified form of the invention.

In producing the fabric illustrated in Fig. 1 a plain web is knit in the usual manner by drawing courses of stitches on all the needles of the series being used, as, for instance, on all the needles of a circular independent needle machine such as is commonly used in knitting ladies seamless stockings. When the point in the knitting is reached at which the anti-run-back course is to be formed, as, for instance, when a point near the top of the leg is reached, a series of loops l is drawn by alternate needles only, So that this series of loops engages the stitches of the'preceding course a in alternate wales only. A second series of loops 2 is then drawn on the intermediate needles only, so Athat they engage the stitches of the preceding course a in the intermediate wales only. This completes the course Z1 so that 1t includes stitchesin each Wale which are of equal length and are preferably of the samelength as the stitches drawn in regular knltting. After the course is thus vcompleted the regular knitting of the plain fabric is continued by drawing loops on all the needles in knitting the course c and the succeeding courses.

u In Fig, 2 a modified form of the invention is illustrated which is better adapted for use in the legs of ladies stockings because of the greater elasticity of the antirun-back course when formed in the manner therein illustrated. In this case the loops 1 are drawn in the same manner as the loops l of Fig. 1 and engage the stitches of the preceding course a in alternate wales only. In completing the course b, however, the loops 2 are drawn onthe intermediate needies, and the yarn is tucked on the alternate needles which are holding the loops 1, so that the tuck stitches 3 are formed when the loops of the succeeding course c are drawn on all the needles.

In both forms illustrated the course of stitches b comprises a plurality of series of loops which aggregate a stitch in each wale, and each series of which engages the stitches of the preceding course a in some of tho wales only. A course of this character will act to effectively arrest and prevent the further running back or raveling of the stitches, in case of the breaking or severing of a stitch in the web. The stitches of the course, being of uniform length, and of substantially the same length as the stitches in the main body of the fabric, do not appreciably modify the appearance of the fabric, and may be formed at any desired intervals during the knitting of a. stocking or other article.

While it is preferred to utilize one of the forms vof the invention shown and described, it will be understood that this is not essential, and that other variations or modifications may suggest themselves which come within the broader scope of the invention.

Having explained the nature and object of the invention, and specifically described the preferred forms thereof, what is claimed 1. The method of forming an anti-runback course in a plain knitted web which consists in drawingstitches of courses of yarn in all the wales to form a plain fabric, then drawing loops of a course of yarn through loops of the preceding course in alternate wales only of the web, and/completing this course of stitches byl drawing loops of a second course of yarn through loops of said preceding course in the intermediate wales only of the web and then continuing the knitting o-f the plain fabric by drawing stitches of succeeding courses of yarn in all the wales.

2 rllhe method of forming an anti-runback course in a plain knitted web which consists in drawing stitches of courses of yarn in all the wales to knit a plain fabric, then drawing loops of a course of yarn in alternate wales only, then completing this course of stitches by drawing loops of a second yarn in ,the intermediate wales and tucking in the alternate wales,iand then continuing the knitting of the plain fabric by drawing loops of succeeding courses of yarn in all the wales. f 3. A plain knitted fabric having in it body an anti-run-back course comprising a series of loops engaging the stitches of the preceding course in some of the wales only, and other series of' loops engaging the stitches of the preceding course in the otherl wales only, the loops of all said series being engaged by the stitches of the succeeding course in all the wales.

4C. A plain knitted fabric having in its body an anti-run-back course comprising a ond series of loops engaging the stitches of said preceding course in the intermediate wales only, the succeeding course of ,stitches engaging both series of loops in said alternate wales and the second series of loops in said intermediate wales.

6. A plain knittedl fabric having in its body an anti-run-back course .comprising a plurality of series of loops aggregating a stitch in each Wale engaging the loop of the succeeding course and each series engaging the preceding course of stitches in some of the wales only.
